SWITCH-STAND.

Specification of Letters Patent.

Patented Au 12, 1919.

Application filed January 19, 1918. Seria1No.212,756.

To all whom it may concern: I

Be it known that I, STANLEY W. HAYES, a

derails, switch points or other track appliances. Its object is toproduce a small operating stand of neat appearance, simple 1n form andextremely rugged in constructlon and economical to manufacture. Thestand in its preferred form comprises five essential parts very easilyput together.

In the accompanying drawings,

Figure 1 is a general perspective view of the improved stand;

Fig. 2 a top plan of the base of the stand with parts broken away;

Fig. 3 a transverse vertlcal cross-section through the axis of thestand;

Fig. 4 a top plan detail of the bell crank member; and

Fig. 5 a sectional detail of the operating handle.

The base of the stand is composed of two opposite flange members 1,provided with spike holes for attachment to the top surfaces of twoadjacent railroad tles. These spike flanges are united by an upstandingarched roof portion 2, and a depressed floor portion 3 disposed belowthe level of the tie tops and adapted to occupy the space between them.Both the roof and floor portions are appropriately braced to the spikeflanges by angle ribs, as shown, and the en- .tire base is formed as asingle or one-piece casting. The roof and floor portions are providedwith shaft bearmgs in vertical alinement. The upper bearing is a drilledhole. The lower bearing may also be a drilled hole or a step bearing ofany su table type. It is preferred, however, to dr1ll both bearings,which can be done in one op eration. The target stafl 4 inserted 1nthese bearings is held in place therein by the sleeve 5 of a crank armmember (separately shown in Fig. 4), which embraces and surrounds thestaff between the bearings and in the space between the roof and floorportlons. This sleeve 5 is set screwed to the target stafi and thereforesupports it vertically, if not otherwise supported, and also secures itagainst removal from the base, as w1ll be evident. The crank arm memberis essentially a bell crank. Its power arm is formed for attachment toan operating handle 6, as presently described, and its other arm isformed for connection with the connecting rod 7 running to the switchpoint or other device to be operated. This lower arm is formed byaneye-bolt 8, threaded into a lug 9 on the crank sleeve, the said lugbeing ec centrically placed with respect to the ,axis of the crank, inorder that the bolt may be screwed in and out as far as necessary togive the proper radius of throw. The end of the eye-bolt 8 is adaptedfor attachment to the connecting rod and will be observed to occupy thenormal level of said rod, just below the level of the tie tops.

The power arm of the bell crank is formed by an integral web 10,extending laterally upward to the exterior of the space between roof andfloor portions, where it carries the pivot 11 for the handle 6. Thelatter is bifurcated or slotted at its end and straddles the end of theweb so as to obtain a secure operating bearing thereon. As shown in-Fig. 5, the handle pivot 11 extends into both cheeks of the bifurcatedend of the handle, and one of said checks is extended beyond the pivotto a position underneath the marginal flange 12 of the roof portion.This extended cheek, marked 13, serves as a latch to engage the slots orshoulders 14 and 15 of the roof flange 12, when the handle is depressedon its pivot, as clearly-indicated in Fig. 1. When in such position, apadlock hole in the crank arm 10 is exposed above the handle, and apadlock hasp inserted therein will retain the cheek extension 13 inengagement with the slot 14 or 15 and thereby lock the switch standagainst operation. When the padlock has been removed the arm can beswung upward to the position indicated in Fig. 3, and until the cheekextension 13 strikes the stop lug 16 formed on the operating arm, and inthis position the switch stand may be operated as desired.

It will be observed that the target staff.

true 10 of the crank sleeve on the same side as the operating handle, isthus in the best position for the transmission of the operating strain,affording a maximum strength for a minimum for metal.

I claim:

1. A switch stand having a base comprising opposite spike flanges unitedby an upstanding roof portion and a depressed floor portion, saidportions being provided with shaft bearings in vertical alinement, atarget Sta-if in said bearings, a crank sleeve secured thereon betweenthe bearings, a lower arm on said crank sleeve adapted for connection tothe operating track member, an upper arm thereon, andv an operatinghandle pivoted on said upper arm and adapted to swing Vertically withreference to said crank sleeve.

2. The switch stand specified in claim 1, having shoulders formed on itsroof portion for interlocking with apart of said operatin handle.

3. he switch stand specified in claim 1, having a web structure on thecrank sleeve serving as said upper arm and incorporating an eccentriclug in which the said lower arm is threaded.

In testimony whereof, I have signed this specification.

STANLEY W. HAYES.
